Iron-catalysed fluoroaromatic coupling reactions under catalytic modulation with 1,2-bis(diphenylphosphino)benzene

A catalytic amount of 1,2-bis(diphenylphosphino)benzene (DPPBz) achieves selective cleavage of sp3-carbon-halogen bond in the iron-catalysed cross-coupling between polyfluorinated arylzinc reagents and alkyl halides, which was unachievable with

Trifluorobenzene derivative and liquid crystal composition containing the same

A trifluorobenzene derivative having a superior stability and a large positive dielectric anisotropy value and a liquid crystal composition containing the derivative are provided, which derivative is expressed by the formula STR1 wherein R is 1-10C alkyl and one --CH2 -- group or two not-adjacent --CH2 -- groups in the alkyl may be replaced by O and/or --CO-- and/or --COO-- and/or --CH=CH--, --A-- and --B-- are 1,4-cyclohexylene, 1,4-phenylene, pyrimidine-2,5-diyl or 1,3-dioxane-2,5-diyl, l and m each are 0, 1 or 2 and l+m≥1, and Z1 and Z2 each are --COO--, --OCO--, --CH2 CH2 --, --OCH2 --, --CH2 O--, --CH=CH-- or single bond and may be same or different.
